BOILER-FEEDER.

.aPECIFIGATION forming part of Letters Patent No. 673,543, dated May 7,1901. Application filed \Tune 15, 1900. Serial No. 20A35. (No modemToall whom it may concern.-

Be it known that 1, CHARLES L. KING, a citizen of the United States,residing in Brooklyn borough, city and State of New York, have inventedan Improvement in Boiler-Feeders, of which the following is aspecification.

My invention relates to supplying steamboilers with water by a new andautomatic device instead of by the usual methods of pumps or injectors.By this new method the water in the boiler can be kept at a properheight without care on the part of the engineer.

The accompanying drawings, forming part of this specification, show thegeneral form and detail of the invention, in which- Figure 1 is anelevation of the feeder in connection with boiler, partly sectional.Fig. 2 is the same view of section with parts in different position.Fig. 3 is a sectional elevation at right angles to Figs. 1 and 2. Fig. 4is a section through valve E as shown in Fig. 3.

Like letters refer to like parts.

The main portion of this invention consists of an outer shell and aninner chamber, the outer shell A being bored out, (preferably larger atone end than the other,) and an inner shell or chamber B, turned andfitted steam and water tight into shell A and capable of being rotatedor oscillated in relation to shell A.

In the outer shell A is an opening A, with water-pipe connection fromreservoir and an opening with pipe A communicating with water-space inboiler M.

S represents an opening in shell A and pipe connection to steam-space inboiler M.

E is an opening through shell A, with checkvalve, as shown in Figs. 3and 4.

In chamber B are openings corresponding to the openings in shell A.

In Figs. 1 and 3 the opening B in chamber B is shown oppositethewater-supply opening A, and in Figs. 3 and 4 is shown the opening Bopposite the valve-opening E.

In Fig. 2 the opening B is shown opposite opening into pipe to boiler AB is a projecting stem or shaft of B, passing through cap-plate F andthrough stuffingbox.

F is a flange on shell A, to which F is secured.

L is a lever fastened to B and operated by connecting-rod L, the rodbeing actuated by any suitable machinery.

In Fig. 1 the water-chamber B is shown in position in relation towater-level in boiler.

The action of this device is as follows: The water-inlet passage A beingopen to chamber B through B, as shown in Figs. 1 and 3, and the openingB being opposite valve E, the other openings being closed, the water canflow by gravity or pressure into the chamber and any air or gas can findexit through valve E until the water reaches the floating valve andcloses the opening. This operation of filling is done while the lever ismoving up to position shown in Fig. 1' and while in that position andwhile the lever moves downward, and with it the chamber B, rotating inshell A, until the opening at A is closed by the solid wall of B passingthe opening A. The lever and the chamber continue to move until theopening B in chamber comes opposite to opening in feed-pipe A At thesame time the opening B will have arrived opposite opening of steam pipeS, when the pressure of steam and water will be equalized and the waterwill flow down to bottom of boiler. The level of the Water in chamberand in boiler will be the same. When the water in the boiler is as highas the top of the chamber, as at m, the chamber will remain full, and asno more water can enter the continued action of the lever and chamberwill have no effect until the level is reduced, when water will flow inat each motion sufiicient to supply the vacancy, so that the device canbe in continual action, requiring no attention from engineer to keep theWater-supply in boiler at correct level.

In Fig. 1 the supply-pipe A is shown to drop below the place where itenters the boiler, as at A The purpose of this is to prevent excess ofheat from the boiler reaching the cham ber B. This can be accomplishedby a sufficient drop of the supply-pipe below the boiler or by asufficient length of supplypipe between the chamber and boiler, andunder some conditions by a check valve, thereby providing for atemperature in chamber 13 lower than the evaporating-point and avoidingback pressure to pipe A and consequent hindrance to water-supply.

Having described my invention, What I desire to claim and secure byLetters Patent 1s In a boiler-feeder, the shell A having inlet S forsteam from boiler, Water-inlet A, wateroutlet A air-vent E with floatingvalve for 10 closing the vent, and a, pipe A to the boiler,

a, portion of the pipe being at a lower level than Where it connects tothe boiler, for purpose described, in combination with the inclosedoscillating chamber Bhaving openings B, B and B substantially as shown.
